Sensitivity
You can configure the sensitivity of detection. Choosing
proper sensitivity will enhance the performance of the
Auto Tracking since the environmental condition may
influence the accuracy of the detection. For instance, rain,
snow, or swaying branches may cause malfunction of auto
tracking.
•
LOW : The sensitivity of the object detection is low.
In this case, if the object is too small or very similar
to the background, it may not be detected.
•
MEDIUM : The sensitivity of the object detection
is middle. The camera detects the object more
accurately than the case of low sensitivity. It
may detect swaying branches or flags, but not
frequently.
•
HIGH : The sensitivity of the object detection is
high. The camera can detect a small object, but it
can also detect swaying branches or flags, rain or
snow.

The camera may detect and track unintended
movements – tree branches, hanging banner, flag,
color change by sudden lighting change, luminous
intensity change by cloud – tracking errors can be
occurred by bright light sources, flickering lights and
dome internal reflections. To prevent and correct
such errors, adjust the direction and angle of the
camera.
•
Tracking errors and degradation by raindrops, snow,
fog, smoke or heat can be occurred.
•
If the camera lens is smeared with foreign substances
or is scratched, tracking errors may occur.
